If you have Automatically Adjust Daylight savings, then yes it will change by 1 hour when it supposed to. If this server is a DC that authenticates logins, then client machines should update to "match" the time on the DC. If times to not "match" then the logon process will error. i don't know of a way to have client machines who authenticates to a DC have a different time that the domain controller that it authenticates to.
